Paper Abstract:
|
This paper proposes a novel system to extract the behavior from digital integrated circuits (ICs), combinational and sequential, by observing its normal operation. An acquisition data system controlled by a computer send measurements of voltage values on the pins of the IC, that is subsequently analyzed on the computer by several algorithms to obtain its behavioral. When an input-output correspondence is found a combinatorial function is made, otherwise heuristically methods are applied to achieve a sequential circuit approach. Extracted behavior is automatically converted into VHDL language description, to synthetize the extracted schematic. Thus, the replica obtained by the system could be structurally improved, assuming the same behavior, so an equivalent circuit has been generated. Due to abstraction level, provided by behavioral description, the obtained replica has a lower dependence of hardware compared to structural approaches |
